Yesterday footage of Kanye West's grand marriage proposal to his baby mama Kim Kardashian surfaced on the internet. The footage shows Kanye get down on one knee while an orchestra plays Lana Del Ray, as he asks for Kimmy's hand in marriage. While the footage is not too high quality, apparently 'Ye and Kim are still upset that it leaked, and could be looking to sue.

TMZ reports that the couple are pissed off that someone secretely taped the proposal, which went down at San Francisco's AT&T stadium. Sources say that the soon-to-be-married couple think they know who leaked it, and that the person signed a confidentiality agreement. Thus, a lawsuit may not be too far away.

We'll keep you posted. Check out the leaked footage below.

[Update: Youtube Co-Founder, Chad Hurley, Leaked Footage]

We now have the name of the person who leaked Kanye and Kim's wedding proposal. According to AHH, YouTube co-founder, Chad Hurley, is the one who released the first video of Kanye West’s proposal to Kim Kardashian at AT&T Field. The 36 year old entrepreneur released the video on his new collaborative app MixBit and spread it globally on his personal Twitter account of over 510,000 followers. 

The release of the video seems to have also been aimed to be a promotion of the new app as Hurley did not only release the video on his Twitter but sent it to a few news publications with a press release, one being Vanity Fair.

Apparently Chad didn't care about the confidential agreement he signed.
